*HOT-AIR REGISTER.

S?EGIFICATION forming part of Letters Patent No. 270,832, dated January16, 1883.

' Application filed November 10, 1882. (No model.)

To all whom it may concern p Beit known that I, PATRICK W. NoLAN, acitizen ot' the United States, residing at New York, in the county andState of New York, have invented new and useful Improvements in Hot-AirRegisters, of which the following is a specification.

This invention relates to a hot-air register which is provided with twosets ot valves, one set being arranged to open inward, while the otheropens outward, both sets being opened y and closed simultaneously by thesame mechanism. n

In the accompanying drawings, Figure l represents a vertical section inthe plane x x, Fig. 2. Fig. 2 is a horizontal section in the plane 1/y,Fig. i. Fig. 3 is a vertical section in the plane z e, Fig. 1, lookingto the right. Fig. 4 is a vertical section in the plane x x, Fig..2.

Similar letters indicate correspondingparts.

ln the drawings, the letter A designates the frame, which is secured inthe inner wall ot' the due F, and in which are mounted two sets ofvalves. B B C, the valves B B being made to open inward, while thevalves O open outward, as shown in Fig. 1. The valves B B swing ongudgeonsbb, Fig. 4, respectively, which have their bearings in the sideplates of the frame A, near their inner edges, and the valves U swing ongudgeons o, the bearings of which are also in the side plate ot' theframe, near their front edges.

Between the gudgeons b, b', and c, close to the inner surface ot one ot'the side plates ot" the frame A, is situated a slide,'D, which isretained by screws d, passing through slots c in the slide,`so that saidslide can be moved up and down. From theinnersurtaceof theslide extend aseries ot' projections, j', which are arranged in pairs, and each pairot' projections acts upon a. spur, g, extending from one ot' the valvesB B O, as shown in Fig. 1, so that by moving the slide down to theposition' shown inFig. l all thevalves are thrown open, and by movingthe slide up all the valves are closed. From the inner surface ot' theslide D, near its bottom end,-pro]`ect two studs, 7L h, between which issituated the. cam-shaped head i of a lever, Emwhich has its fulcrum onone of thescrews d. This head is so formed that by turning the lever Ein one direction the slide D is moved down, and by turning said lever inthe opposite direction the slide D is moved up. By these means apositive movement can be imparted to all the valves. The mechanism issimple and cheap in its construction. 1t must be remarked, however, thatthis mechanism might be changed without departing from the main pointot'my invention, and 6o l do not wish to coniine myself', therefore, tothe precise mechanism shown inthe drawings.

By referring to Fig. l it will be seen that the valve B is ot' greaterlength than the valve B',

so that when the slide D is moved clear down the outer edge of the valveB strikes the outer wall of the due F, while theouter edge ot' the valveB' leaves a free passage up through the ue fora portion ofthehotair,while another portion is deiiected and thrown against the valves 7o C,and by these valves downwardinto the room. The outer edge of the valveBis provided with a. recess,j, so that the passage ot the hot air, upthrough the liuc is not entirely stopped when this valve is thrown wideopen; but

while a small portion of the hot air can still ascend through the tluethe largest portion of the hot air is deflected against the valves C,and by these valves into the room. In order to insure this action, theupper ends of the 8o valves `B Bextend somedistance beyond their gudgens, as seen in Fig. 1.

By means ofthe lever E the position ot' the valves B B O can heregulated so that more or less ot' the hot airescapesintotheroom con- 85taining the register, and the temperature of the room can be regulatedwith little trouble.

What I claim as new, and desire to secureby Letters Patent, is-
